The students were given materials to create an experiment that hummed and then made a dinging sound. The results are amazing!


At first we were going to attach a paper clip or binder clip to the motor, but we didn't do that. We actually attached the bell to the motor so it could wind up and then ring. Here are the steps to making our humdinger: First you put some wooden sticks in 4 holes, and put the battery case on top of 2 of them and attach the motor. Next you put the bell on a rubber band and tape it to the motor. Then you attach a paperclip to a wire holder on the case and tie a string to the wire then put the wire in the paperclip. Finally pull the string and it HUMS and DINGS! Kasey/Nick☺☻☺☻

Aeron and I made a humdinger the first step of how to make ours is a battery, a battery case, and a cheap little motor with electric wires on and connect the wires to the battery pack.Aeron/Brenden Now you have a working motor. But don't get too excited yet. You have to make the motor turn on and off. So to do that you haft to put a rubber band around the battery case adapter put the motor wire on it put another rubber band on top of it. the motor wire is now a switch but so it does not come out wile you are playing with it tape the motor wire down to the battery pack. Tie a string at the end of the motor that is now in between the wire and two rubber bands. why do that because win you pull it is a switch. For the ding part stick some sticks is the pattern Brenden and I did in the pic to the third one to the top row third one to the right. Put a rubber band around all the sticks. Ok now get the string/switch and the rubber band around the sticks and the bell now get a clothespin and get them all together and close the pen. (P.S. where to put all that stuff together in the pic. hint, hint.) Now pull and wallah. Aeron

My partner was Emme. To make a humdinger like ours you have to get about 4 rubber bands, a D-cell, a battery case, string, a bell, masking tape, a motor, board, and a board holder (like the one in the picture). What we did first was: we put our D-cell in the battery case and tested our motor. Then we tried to figure out a way to get our machine to work. It took us a couple of tries to figure it out, but we finally got it to work with one string to make the hum sound and the ding sound with a second string. Justin (-'-'-).Hi I'm Emme I worked with Justin. Our Humdingers where hard but we did it! I came up with the idea to use two strings,that made it easier.

First, we put 3 sticks in the board, and then hubs on the sticks. Next, Joseph and I put the battery in a cell holder and taped it to two sticks below the first sticks. After that we put the bell on a string and attached the combination to a wire on the motor, but we put the other wire on the cell holder. Then when you pulled the string, it would ding and then the wire (pulled by the string) hit the copper on the cell holder and hummed. So it was was a Ding Hummer! So, I thought we had to reverse it somehow. Joseph put a stick out farther away from the board so the bell would hit it. I reminded him it had to be able to work in a bag like Mrs. T.'s. Finally, overnight I thought up a plan. The next day I told it to Joseph, and I tried it. Here it is: when you pull the string (without the bell) it hits the copper, and then the bell would be hanging behind it. When you let go (Bam!) it would hit the bell. Ding! A Humdinger. Jack <(-_-)>

First, we put the battery in the battery holder. Then, we put 2 sticks in the board. Next, we put a wire from the motor into one of the clips and put the battery holder and the battery onto the sticks. Finally, we taped part of the other wire onto the battery, so it wouldn't fly away. We taped the string to the un-taped part of the partially taped wire, wove the rest of the string through a hole in the board. We pulled and had the humming sound! I thought that that was going to be really hard, but the bell was the hard part. My partner and I (oh yeah, my partner was Alex) ended up threading the string through the hole on the top of the bell and threading the string back through the hole in the board; therefore when you pull softly it hums, and when you let go of the string, it shakes the bell and dings! We had a humdinger !!!!!Casey

First, we got all are tools to make the humdinger. We had a great idea, but it didn't turn out so well.So we tried something else. We put the D-Cell battery in the holder. Then we attached a string to the bell. When we did that we put the wire in front of the metal and pulled the string. It worked. Then a couple days later it was taken apart by somebody so basically we had to start all over . Finally we put it back together and it worked!!!!!!!! Connor - Erin

First, we did the hum and that was the easy part, but then we had to get the ding which was the hard part (ha ha). We tried several different things like we tried to make the hum louder but when we tried that the string got tied around the motor and it made a fan he he! Then we had the bell slam against the stick and d-cell holder so it dinged. The motor was simple all you had to do is put the wires on each side,but it was hard to redo the motor without fixing it every time. We used a rubber band to secure it in place last we had to make the hum louder so we stuck the spinning part of the motor in the hole of the board and taped it on. we got confused with the battery because we stuck the tape on the motor so we thought the battery ran out of power we through it away and go a new one that one didn't work so we looked at the motor and saw the tape.

First, we got all the materials that we needed. Then we brainstormed what we would do with the humdinger to make it work well. Next, we started to build the humdinger. It did not work at first, but then after at least 3 days we got it. Finally, we showed to the class and Mrs.T. said "There is no right or wrong to this project." So try it at home sometime. Just to tell you it is not an easy project, but it is so much fun and challenging!!!! ( :Hannah, Nicholas, Megan, and McKenzie: )
